Giving what a crucible physicaly is, the teaser is most likely for survival/arena mod, not for an expansion. How much did development of a single act area took? Around 7 months for the longest act3. So a solid expansion should take no less then that, the game reached release not even 4 months ago and Crate was busy polishing existing bugs with getting up with backer rewards. Wild guess is that we won't hear about anything expansion related till it'll hit the works, probably autumn this year

possible, but to me it can go either way.

The definition of crucible I found is

Quote:

1. a container of metal or refractory material employed for heating substances to high temperatures.
2. Metallurgy. a hollow area at the bottom of a furnace in which the metal collects.
3. a severe, searching test or trial.

obviously only #3 applies here and that can really mean a new act as much as survival mode

agreed, it should take about that long. As you said it released 3 months ago (just looked it up, 2/25). Summer goes from 6/20 to 9/21, so a September release date gives them 6+ months.

Factor in that the artists were done with the acts before the game was released (as the devs were still working on it) and they easily had those 7 months to work on it by then... so I would not rule out an expansion, but obviously we do not know one way or another until Crate gets a little more specific.
